Estimated surface NO2 over Europe for the year 2019-2021

<p>These datasets consist of estimated daily surface NO₂ concentrations over Europe at ~1km spatial resolution in tiff file format generated using S-MESH model and is part of the research article&nbsp;https://doi.org/10.1016/j.rse.2024.114321. &nbsp;Files are zipped into 3 folders each corresponding to a year and can be unzipped from command line using "tar -xvzf filename.tar.gz". Each file represents surface NO₂ during the Sentinel-5P satellite overpass time and the file is named based on the date of measurement. Each tiff file is a single band image with an extent of 25&deg;W-42.5&deg;E &amp; 29.9-74.28&deg;N in EPSG:4326 - WGS 84 projection. The surface NO₂ concentrations are estimated using Sentinel-5P TROPOMI tropospheric column density and a XGBoost machine learning model. The overall median absolute error of the model predictions across Europe is 4.43&mu;g/m^{3 &nbsp;}</p> <p><strong>Summary</strong></p> <ul> <li>Data: NO₂ concentrations over Europe at ~1km spatial resolution</li> <li>Time Period: 2019-2021</li> <li>Methodology: Using Sentinel-5P TROPOMI NO2 and XGBoost&nbsp;</li> </ul> <ul> <li><span>More information in the article </span><span><a href="https://www.sciencedirect.com/science/article/pii/S0034425724003390#s0155" target="_blank" rel="noopener"><span>https://authors.elsevier.com/sd/article/S0034-4257(24)00339-0</span></a></span><span> or </span><span><a title="Persistent link using digital object identifier" href="https://doi.org/10.1016/j.rse.2024.114321" target="_blank" rel="noopener"><span>https://doi.org/10.1016/j.rse.2024.114321&nbsp;</span></a></span></li> </ul>
